Abstract
An abrasive is made by fusing in the electric furnace preferably calcined diaspore, iron such as ground cast iron borings, and coke, preferably in the proportions of 17 : 2 : 3, and cooling slowly with or without agitation. It consists of corundum with some ferro-silicon; no slag is formed.
